DUBLIN, Ireland – In yet another Distributed Denial of Service (DDOS) attack by hackers reported in Ireland, the country’s biggest telco said that its email system suffered a suspected attack.

The attack, suspected to be a DDOS attack, which is a malicious attempt to make a server or a network resource unavailable to users is said to have put 400,000 of Eir users at risk.

Customers with @eircom.net addresses reportedly began experiencing problems accessing their mail following the suspected attack.

Following the reports, Eir said it noticed the issue and immediately began its mitigation process.

A DDOS attack usually is launched by interrupting or suspending the services of a host connected to the internet.

Reports quoted an Eir spokesman as saying that a majority of its customers should be able to access their emails accounts again.

The spokesperson even said that the firm had received no contact with any hackers or any ransom demand.

According to reports, users might still face issues even as the mitigation process continues to scan through IP addresses to sort out the genuine ones from those that might have been part of an attack.
